The housing comprises an internal protective cover (15), an outer protective cover (16) extending around the inner protective cover (15) and a hollow arm (18) connecting the outer protective cover (16) to the inner protective cover (15), each hollow arm (18) is intended to receive a tubular auxiliary element (21), and each hollow arm (18) defines an inner housing (180) connecting a first through-hole (150) through the inner protective cover (15) in a radial direction (DR) with a second through-hole (160) through theouter protective cover (16) in the radial direction (DR), and includes an inner wall (182) facing the inner housing (180). Each arm (18) comprises at least one projection (185a, 185b, 1850a, 1850b) on said inner wall (182) of the arm (18), the protruding portion protrudes from the inner wall (182) toward the inner housing (180) and defines a constricted portion (188, 1880) of the inner housing (180) in a cross-section orthogonal to an extending direction of the arm (18).
